Widespread Convection over the central U.S.

It’s spring time on the Great Plains, which means strong dynamical systems that often bring blizzards as well as severe thunderstorms. A long-wave trough with an embedded 850-500mb jet streak created cyclogenesis in western Oklahoma and southwest Kansas on March 13, with associated low-level moisture return into eastern Kansas.The strong...

Severe Weather in North Texas

The North Texas panhandle is experiencing severe weather on October 4, 2023. Animation 1 shows Radar reflectivity in tight areas of convection across the panhandle. The GOES Day Cloud Phase Distinction RGB shown in Animation 2 confirms convection, showing overshooting tops becoming wispy ice clouds (appearing orange in the RGB).An enhanced risk of convection...

Supercells in the Southeast

A cold front with ample moisture and instability ahead of it spawned numerous strong storms in the Southeast U.S. yesterday; particularly one long-lived supercell in South Carolina. A convolutional neural network model (CNN) was deployed in realtime on the 1-min GOES-16 mesoscale sector imagery. The model produces an “Intense Convection... Read More
